PCIe hot swap is not supported for graphic controllers (e.g. FMM-5002E) installed on a
RTM.
2.2.5 Redundant BIOS Flash
The MIC-5332 has two SPI flash devices for storing redundant x86 firmware (BIOS,
BIOS configuration, etc.). The integrated management controller (IPMC) controls
which flash device is active. Failover and rollback operations between the flash
devices are compliant to HPM.1. By default, the MIC-5332 starts to boot from the
active BIOS chip and will switch to the backup BIOS chip if it detects a problem, i.e.
the BIOS is stuck in POST or fails to boot. For more details, please refer to Chapter 5,
about AMI BIOS setup. From OS side of view, there is only the active BIOS SPI flash
visible at any time.
2.2.6 Serial ATA and Serial Attached SCSI Controller
The MIC-5332 supports a total of 6 SATA and 4 SAS lanes.
The built-in Serial ATA (SATA) and Serial Attached SCSI (SAS) controller in the
Intel® C600 PCH has three modes of operation to support different operating system
conditions. In the case of a Native IDE enabled operating system, the C600 PCH
utilizes two controllers to enable all six ports of the bus. The first controller (Device 31:
Function 2) supports ports 0-3 and the second controller (Device 31: Function 5)
supports ports 4 and 5. When using a legacy operating system, only one controller
(Device 31: Function 2) is available which supports ports 0-3. In AHCI or RAID mode,
only one controller (Device 31: Function 2) is utilized, enabling all six ports and the
second controller (Device 31: Function 5) will be disabled. Please contact your
Advantech technical support team for more detail information.
In the MIC-5332, SATA 6 Gbps support is available on PCH Ports 0 and 1 only, and
reserved for onboard storage modules like CFast or 2.5” SSD. For detailed
configurations, please refer to table 2.4:
